2019.2 Zynq UltraScale+ MPSoC: PetaLinux ZCU106 BSP fails to detect SD Card FAT32 or EXT4 partition when booting Linux

 

Solution

This is a known issue in the 2019.2 ZCU106 BSP.

To fix this issue, you will need add device-tree node property to <plnx-proj-root>/project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi

1) Modify the system-user.dtsi file with below content:

$ vim <plnx-proj-root>/project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi

# system-user.dtsi content 

"/include/ "system-conf.dtsi"
/ {
};

&sdhci1 {
        no-1-8-v;
};

 

2) Clean the device-tree sstate cache and rebuild the device-tree:

$ petalinux-build -c device-tree -x cleansstate

$ petalinux-build -c device-tree

 

Note: This solution also applies to the 2019.2 ZCU106 VCU TRD PetaLinux BSP.
